Predicted to enable metal ion binding activity. Predicted to be involved in exocytosis and positive regulation of exocytosis. Predicted to act upstream of or within cellular response to starvation; hematopoietic stem cell homeostasis; and synaptic vesicle priming. Predicted to be located in several cellular components, including nucleoplasm; parallel fiber to Purkinje cell synapse; and synaptic membrane. Predicted to be active in glutamatergic synapse. Orthologous to human CADPS2 (calcium dependent secretion activator 2). [provided by Alliance of Genome Resources, Apr 2022]
